Testing concrete - Recommendations for the measurement of dynamic modulus of elasticityWhat is BS 1881 209 Dynamic modulus of elasticity of concrete about? The modulus of elasticity of concrete is used in the calculations of structural deformations. BS 1881 is a British Standard series that discusses methods for testing of concrete. The main aim of the BS 1881 series is to provide best industry recommendation on tests to determine whether your concrete and concrete products are fit for purpose. BS 1881 209 is the 209th part of the
